Description
One-Part Cementitious-Polymer Modified Waterproof Mortar & Slurry
A single-component, polymer-modified, cement-based waterproofing slurry that incorporates advanced micro silica polymer and fibre technology. When cured, it creates a dense matrix with very high adhesion that is impermeable to water to 10 bar of water pressure to both the positive and negative pressure sides of the structure.
HydroSeal 105 1K waterproofing slurry
HydroSeal 105 1K is supplied as a single-component system, requiring only the addition of clean water to form a mortar, a suitable bag-rubbing mix, a surface repair product, a fairing coat/thin section bonded screed, and a waterproofing render. Add slightly more water or tanking slurry and apply by spray by airless machine.
HydroSeal 105 1K is one product with five uses. Keep a bag on the van at all times.
Key Benefits
- 2 mm slurry coat is fully waterproof and resists 10 bar positive and negative water pressure
- Environmentally friendly, water-based product, ideal for use in confined spaces
- Can be part-mixed
- Can be applied as a mortar to 6 mm thickness and so can be used to waterproof, smooth and/or repair rough and uneven surfaces in just one application
- Strong with quick strength gain – 13 MPa within 1 day
- Quick drying times – rain tight within 1 hour
- Odourless and VOC free
Typical Waterproofing Applications
- Waterproofing of structural concrete
- Waterproofing of structural masonry
- Waterproof smoothing or fairing coat for rough faced surfaces
- Waterproof surface repair
- Waterproof levelling and repair to floors
- Filling surface pinholes to concrete and smoothing rough-faced block walls using bag rubbing technique
